RESUMEN
Background and Objectives: Community emergency departments often transfer patients for lack of neurology coverage, potentially burdening patients and accepting facilities. Telestroke improves access to acute stroke care, but there is a lack of data on inpatient teleneurology and telestroke care. Methods: From our prospective telestroke registry, we retrospectively reviewed 3702 consecutive patients who were seen via telestroke between September 2015 and December 2018. Patients who required transfer after initial telestroke evaluation or who were kept at hospitals without consistent neurology coverage were excluded from analysis. We compared baseline demographics, clinical characteristics, and hospital outcomes in patients who were subsequently followed remotely by a teleneurology neurohospitalist and those followed in person by a neurohospitalist. Results: There were 447 (23%) patients followed by a teleneurology neurohospitalist and 1459 (77%) patients followed in person by a neurohospitalist. Both groups presented with similar stroke severity. In multivariate analysis, there were no significant differences in discharge disposition, stroke readmission rates, or 90-day modified Rankin Scale (mRS) scores. Length of stay was shorter with teleneurology follow-up. In the subgroup of patients who received tissue plasminogen activator, patients showed no differences in outcomes and had similar complication rates. Teleneurology follow-up resulted in a 3% transfer rate for higher level of care after admission. There remained no difference in outcomes in a subanalysis without Comprehensive Stroke Centers. A higher proportion of non-Hispanic Black patients and a lower proportion of Hispanic patients in the teleneurology follow-up group were possibly due to spoke location demographics. Discussion: Teleneurology follow-up resulted in comparable outcomes to in-person neurology follow-up, with few transfers after admission. For select neurology and ischemic stroke patients, teleneurology follow-up provides an alternative to transfer for hospitals lacking neurology coverage.
RESUMEN
BACKGROUND: Recent studies have shown that tPA can be safely administered past the standard 4.5 h window with good outcomes when selected with multi-model imaging, which is often lacking outside of comprehensive stroke centers. AIM: We aim to analyze the safety and outcomes of wake up/unknown onset (WUS/UNK) patients treated based on non-contrast head CT (NCCT) at our institution and in the literature. METHODS: Suspected stroke patients from January 2015 to December 2018 receiving tPA within 4.5 h (standard window-SW) and with WUS/UNK based on NCCT and clinical-imaging mismatch were identified. We compared baseline characteristics, tPA metrics, and outcome data, with primary outcome as symptomatic intracerebral hemorrhage (sICH). A meta-analysis was performed evaluating NCCT-based treatment of WUS/UNK patients. RESULTS: Of 1827 patients treated at our hub or through telestroke, 93 underwent WUS/UNK-based treatment. There was no statistical difference in sICH between WUS/UNK and SW: 1% vs. 4% (OR 0.3; 95% confidence interval 0.0-1.9). 90-day modified Rankin scale outcomes were similar between SW and WUS/UNK-treated patients. Seven studies encompassing 485 WUS/UNK patients were included in a pooled analysis with a 2.1% incidence of sICH. In our meta-analysis, three studies compared NCCT-based treated WUS/UNK patients with SW patients with no difference in rate of hemorrhage: 2.1% vs 3.4% (OR 1.01; 95% confidence interval 0.45-2.28). INTERPRETATION: Our single-center analysis and meta-analysis suggest that tPA can be safely administered based on NCCT with comparable rates of sICH for select WUS/UNK stroke patients.

INTRODUCTION: In a telestroke network, patients at a referring hospital (RH) with large-vessel occlusion (LVO) are transferred to a comprehensive stroke centre (CSC) for endovascular thrombectomy (EVT). However, a significant number of patients do not ultimately undergo thrombectomy after CSC arrival. METHODS: Within a 17-hospital telestroke network, we retrospectively analysed patients with suspected or confirmed LVO transferred to a CSC, and characterized the reasons why these patients did not undergo EVT based on the 2019 American Heart Association guidelines. RESULTS: Of 400 patients transferred to our hub, 68 (17%) were based on vascular imaging at RH. Time from RH arrival to neuroimaging was significantly longer in patients that underwent both computed tomography (CT) and CT angiography of the brain and neck compared to only CT of the brain (53 vs 13 minutes, p < 0.05). Accuracy of anterior circulation LVO (ACLVO) detection based on clinical suspicion was 62% (205 of 332 patients). Among 234 ACLVO patients, overall, 175 (74%) (early window group: 123 (73%) patients and late window group: 52 (80%) patients) met at least one EVT ineligibility criterion. The reasons for EVT ineligibility varied from large core infarct (aspects <6 or core volume >70 cc on perfusion imaging in late window), low National Institutes of Health Stroke Scale (<6), distal occlusion, and poor baseline modified Rankin Scale score (>1). DISCUSSION: Instituting rapid acquisition and interpretation of vascular imaging at RHs for LVO detection and establishing benchmarks for door to vascular imaging is urgently needed for RHs.

BACKGROUND: Tissue plasminogen activator (tPA) refusal is 4%-6% for acute ischemic stroke (AIS) in the emergency department. Telestroke (TS) has increased the use of tPA for AIS but is accompanied by barriers in communication that can affect tPA consent. We characterized the incidence of tPA refusal in our TS network and its associated reasons. METHODS: Patients with AIS who were offered tPA within 4.5 hours from symptom onset according to American Heart Association guidelines were identified within our Lone Star Stroke Consortium Telestroke Registry from September 2015 to December 2018. We compared baseline characteristics and clinical outcomes between patients who refused tPA and patients who accepted tPA. RESULTS: Among the 1,242 patients who qualified for tPA and were offered treatment, 8% refused tPA. Female and non-Hispanic Black patients and patients with a prior history of stroke were more likely to decline tPA. Patients who refused tPA presented with a lower NIHSS and were associated with a final diagnosis of stroke mimic (odds ratio [OR] 0.23; 95% confidence interval [CI] 0.15-0.36). Good outcome (90-day modified Rankin Scale 0-2) was the same among patients who received tPA and those who refused (OR 0.80; 95% CI 0.42-1.54). The most common reasons for refusal were rapidly improving and mild/nondisabling symptoms and concern for potential side effects. CONCLUSION: tPA refusal over TS is comparable to previously reported rates; there was no difference in outcomes among patients who received tPA compared with those who refused. Sex and racial differences associated with an increased tPA refusal warrant further investigation in efforts to achieve equity/parity in tPA decisions.
RESUMEN
OBJECTIVE(S): Coronavirus disease 2019 (COVID-19) presents an enormous challenge to healthcare systems globally. Optimizing access to healthcare while minimizing face-to-face patient encounters is critical to limiting exposures, conserving resources, and preserving health. We aimed to evaluate the utility of a COVID-focused telehealth program in avoiding potential in-person visits while maintaining high patient satisfaction. METHODS: All patients with COVID-related virtual visits at our center between March and May 2020 were included. Demographic, satisfaction, and clinical information were gathered using a modified, validated telehealth satisfaction questionnaire disseminated via email or telephone. Data were analyzed using Stata. RESULTS: Of 581 eligible patients, 180 (31%) responded to the survey. Symptoms (73%) and possible exposure (22%) were the main reasons cited for pursuing a virtual visit; cough (44%) and fever (36%) were the most common presenting symptoms. Regarding patient satisfaction, most patients rated the experience as "very good" or "excellent", and 94% of respondents said they would recommend COVID-focused triage through telehealth to others. Over 81% of patients indicated that, if telehealth was not an option, they would have sought an in-person encounter. Ultimately, only 27% of patients reported pursuing a face-to-face encounter after participating in the virtual visit. CONCLUSION: Based on patient self-reporting, telemedicine potentially prevented face-to-face COVID-related encounters. Patients expressed satisfaction with the virtual process and were less likely to pursue in-person consultation. Leveraging a telehealth strategy for forward triage has the potential to reduce exposures while conserving healthcare resources.

OBJECTIVE: We aim to report intra-arterial thrombectomy transfer metrics for ischemic stroke patients that were transferred to hub hospitals for possible intra-arterial thrombectomy in multiple geographic regions throughout the state of Texas and to identify potential barriers and delays in the intra-arterial thrombectomy transfer process. METHOD: We prospectively collected data from 8 participating Texas comprehensive stroke/thrombectomy capable centers from 7 major regions in the State of Texas. We collected baseline clinical and imaging data related to the pre-transfer evaluation, transfer metrics, and post-transfer clinical and imaging data. RESULTS: A total of 103 acute ischemic stroke patients suspected/confirmed to have large vessel occlusions between December 2016 to May 2019 that were transferred to hubs as possible intra-arterial thrombectomy candidates were enrolled. A total of 56 (54%) patients were sent from the spoke to the hub via ground ambulance with 47 (46%) patients traveling via air ambulance. The median spoke arrival to hub arrival time was 174 min, median spoke arrival to departure from spoke was 131 min, and median travel time was 39 min. The spoke arrival time to transfer initiation was 68 min. CT-perfusion obtained at the spoke and earlier initiation of transfer were statistically associated with shorter transfer times. CONCLUSION: Transfer of intra-arterial thrombectomy patients in Texas may take over 4 h from spoke arrival to hub arrival. This time may be shortened by earlier transfer initiation and acceptance.

INTRODUCTION: Differences in access to stroke care and compliance with standard of care stroke management among patients of varying racial and ethnic backgrounds and sex are well-characterized. However, little is known on the impact of telestroke in addressing disparities in acute ischemic stroke care. METHODS: We conducted a retrospective review of acute ischemic stroke patients evaluated over our 17-hospital telestroke network in Texas from 2015-2018. Patients were described as Non-Hispanic White (NHW) male or female, Non-Hispanic Black (NHB) male or female, or Hispanic (HIS) male or female. We compared frequency of tPA and mechanical thrombectomy (MT) utilization, door-to-consultation times, door-to-tPA times, and time-to-transfer for patients who went on to MT evaluation at the hub after having been screened for suspected large vessel occlusion at the spoke. RESULTS: Among 3873 patients (including 1146 NHW male (30%) and 1134 NHW female (29%), 405 NHB male (10%) and 491 NHB female (13%), and 358 HIS male (9%) and 339 HIS female (9%) patients), we did not find any differences in door-to consultation time, door-to-tPA time, time-to-transfer, frequency of tPA administration, or incidence of MT utilization. CONCLUSION: We did not find racial, ethnic, and sex disparities in ischemic stroke care metrics within our telestroke network. In order to fully understand how telestroke alleviates disparities in stroke care, collaboration among networks is needed to formulate a multicenter telestroke database similar to the Get-With-The Guidelines.

INTRODUCTION: We aimed to identify factors associated with rapid infarct progression during inter-facility transfer for endovascular thrombectomy evaluation and its impact on clinical outcomes. METHODS: Patients with anterior circulation large artery occlusion within 24 h of onset transferred within our 17 hospital tele-stroke network were retrospectively analyzed. Patients were divided into fast progressors and slow progressors. Fast progressors were defined as CT ASPECTS score of ≥6 at the referring hospital (RH) and <6 at the hub hospital. Good clinical outcomes were defined as modified Rankin Scale score (mRS) 0-2 at 90 days. Demographic, clinical and radiologic variables associated with fast progressors and good clinical outcomes were identified using multivariable regression models. RESULTS: Among the 190 patients, 44 (23%) patients underwent rapid infarct progression. Higher stroke severity at presentation [aOR, 1.096, 95% CI,1.023, 1.174; p = 0.009], presence of early ischemic changes (CT ASPECT 6-9) at the RH [aOR, 2.721, 95% CI, 1.22, 6.071; pâ¯=â¯0.014] were positively associated, whereas prior ischemic stroke [aOR, 0.272, 95% CI, 0.078, 0.948; pâ¯=â¯0.04] and higher collateral score (2,3,4) [aOR, 0.138, 95%CI, 0.059, 0.324, p=<0.0001] were negatively associated with rapid infarct progression. Fifty-eight (31%) transferred patients had good outcomes. After adjusting for reperfusion status, age [aOR, 0.96, 95% CI, 0.93, 0.98; p=<0.001], initial stroke severity [aOR, 0.87, 95% CI, 0.81, 0.93; p=<0.001], absolute rate of decrease in CT ASPECTS [aOR, 0.38, 95% CI, 0.19, 0.77; pâ¯=â¯0.007] and internal carotid artery (ICA) occlusion [aOR, 0.34, 95 %CI, 0.12, 0.94; pâ¯=â¯0.038] were negatively associated with good outcome. CONCLUSION: Higher stroke severity, presence of early ischemic changes at the referring facility, absence of prior stroke, and poor collateral scores (CS 0-1) are the factors associated with rapid infarct progression in the telemedicine transfer cohort. Increasing age, higher stroke severity, higher absolute decrease in CT ASPECTS and ICA occlusion determine poor clinical outcomes.

INTRODUCTION: The Lone Star Stroke Consortium Telestroke Registry (LeSteR) currently consisting of 3 academic hub centres and 27 partner spokes is a statewide initiative organised by leading academic health centres in the State of Texas to understand practice patterns of acute stroke management via telestroke (TS) in Texas, a state with one of the largest rural populations in the USA. METHODS AND ANALYSIS: All patients who had presumed stroke for whom a TS consultation has been obtained in the network are entered into a web-based, Health Insurance Portability and Accountability Act-compliant database from September 2013 to present. Spokes were enrolled into LeSteR in a staggered approach in two data collection phases: a retrospective phase and a prospective phase. Basic clinical, demographic data and relevant time metrics are collected in the retrospective phase. Starting 1 September 2015, additional outcome data including 90-day modified Rankin score, readmission and 90-day disposition are obtained by a standard phone interview. From the registry initiation to 31 December 2017, there are 8089 patients who had suspected stroke in the registry. Over 60% of patients enrolled after 1 September 2015 have reported outcome data. Enrolment is still active for this registry. ETHICS AND DISSEMINATION: LeSteR is a statewide TS registry organised by academic health centres that will provide significant insight regarding the impact of TS in the State of Texas. Findings from LeSteR will provide data that can be analysed to improve the allocation of healthcare resources using TS to treat stroke in a state with one of the largest rural populations.

INTRODUCTION: Telestroke has increased access to acute management of ischemic stroke in areas that lack stroke care expertise, yet delays persist in evaluation and treatment. We describe variation in time to alert a telestroke physician of suspected acute ischemic stroke patients potentially eligible for acute stroke therapies among community hospitals in our telestroke network, and explore demographic and spoke-related characteristics associated with delays. METHODS: From our telestroke registry, we identified suspected acute ischemic stroke patients who arrived within 6 hours of symptom onset and underwent video consultation at 1 of 17 community hospitals in our hub-and-spoke network. We compared time between patient arrival to telestroke alert (door-to-page-time) and to tissue plasminogen activator (tPA) administration for eligible patients (door-to-needle-time). We identified factors associated with prolonged metrics. RESULTS: Of 1020 cases between 9/2015 and 3/2017, 47% received tPA. Sixty percent had door-to-page-time more than 15 minutes (median 19.5; IQR, 11-34). Door-to-page-time more than 15 minutes was associated with an 8-fold increase in likelihood of door-to-needle-time more than 60 minutes. Patients with severe stroke experienced faster door-to-page-times. Hospitals with more beds had prolonged door-to-page-time. Full time in-house neurology presence, even when not covering emergent consultations, was associated with faster door-to-page-time over telestroke. Seventy-one percent of patients underwent CT brain prior to the telestroke physician alert; this scenario delayed door-to-page and door-to-needle times. CONCLUSIONS: Door-to-page-time varied considerably among spokes. Awaiting CT scan prior to alerting the telestroke consultant of a stroke code delayed metrics. Telestroke physician alert standards are needed, as are educational initiatives on acute ischemic stroke management and workflow.

Background and Purpose- Telemedicine is increasingly utilized for intravenous tPA (tissue-type plasminogen activator) delivery. The comparative safety of leaving tPA-treated patients at a presenting (spoke) hospital (drip-and-stay) or transferring patients to a central treating (hub) hospital (drip-and-ship) is not established. We sought to compare outcomes between drip-and-ship and drip-and-stay patients treated with tPA via telemedicine. We hypothesized that there would be no differences in short-term outcomes of in-hospital mortality, length of stay, or discharge disposition or in 90-day outcomes between groups. Methods- We retrospectively identified patients treated with tPA at 17 spoke hospitals between September 2015 and December 2016. Demographic, clinical, and outcome data were obtained from a prospective telemedicine registry. We used negative binomial, multinomial, and logistic regression analyses to evaluate length of stay, discharge disposition, and inpatient mortality, respectively. We compared the proportion of patients with 90-day modified Rankin Scale score <2 by group. Results- Among 430 tPA-treated patients, 232 (53.9%) were transferred to the hub after treatment. The median arrival National Institutes of Health Stroke Scale score was higher for drip-and-ship (10; interquartile range, 5-18) compared with drip-and-stay patients (6; interquartile range, 4-10; P<0.001). Unadjusted length of stay was longer in drip-and-stay patients (incidence rate ratio, 0.82; 95% CI, 0.71-0.95). There were no significant differences in adjusted length of stay, hospital mortality, or discharge disposition. Among the 64% of patients with complete 90-day modified Rankin Scale score, the proportion with good outcomes (modified Rankin Scale score <2) did not differ between groups. Conclusions- We found no differences in measured outcomes between drip-and-ship and drip-and-stay patients treated in our network, although our study may be underpowered to detect small differences.

BACKGROUND: Stroke outcomes have been shown to be worse for patients presenting overnight and on weekends (after-hours) to stroke centers compared with those presenting during business hours (on-hours). Telemedicine (TM) helps provide evaluation and safe management of stroke patients. We compared time metrics and outcomes of stroke patients who were assessed and received intravenous recombinant tissue plasminogen activator (IV-tPA) via TM during after-hours with those during on-hours. METHODS: Analysis of our TM registry from September 2015 to December 2016, identified 424 stroke patients who were assessed via TM and received IV-tPA. We compared baseline characteristics, clinical variables, time metrics, and outcomes between the after-hours (5 pm-7:59 am, weekends) and on-hours (weekdays 8 am-4:59 pm) patients. RESULTS: Of the 424 patients, 268 were managed via TM during after-hours, and 156 during on-hours. Baseline characteristics and clinical variables were similar between the groups. Importantly, there were no differences in all relevant time metrics including door to IV-tPA bolus time. IV-tPA complications (including all intracerebral hemorrhage (ICH), any systemic bleeding, and angioedema), discharge disposition, and 90-day modified Rankin Scale were also similar in the groups. CONCLUSIONS: There was no difference in IV-tPA treatment times, acute stroke evaluation times, or mortality between the patients treated after-hours versus on-hours. Unlike in-person neurology coverage at many centers, the coverage provided by TM does not differ depending on the hour or day. Access to stroke specialists 24/7 via TM can ensure dependable and timely clinical care for acute stroke patients regardless of the time of day or day of the week.

BACKGROUND AND PURPOSE: Formal telestroke training for neurovascular fellows (NVFs) is necessary because of growing use of telestroke technologies in the management of acute ischemic stroke; yet, educational approaches and training benchmarks are not formalized. Time between telestroke consultant page and tissue-type plasminogen activator administration (page-to-needle time, PTNT) can provide an objective measure of proficiency. We compared PTNT between NVFs and neurovascular attendings (NVAs) and evaluated changes in PTNT with experience. METHODS: We identified suspected acute ischemic stroke patients in our telestroke registry from July 2013 to December 2015 who received tissue-type plasminogen activator. Using multivariable quantile regression, we estimated the difference and 95% confidence interval in median PTNT between NVFs and NVAs. We also report the coefficient of change in PTNT over increasing number of telestroke consults. RESULTS: NVFs evaluated 53.7% of 618 tissue-type plasminogen activator cases over telestroke. NVAs had significantly shorter PTNT compared with NVFs, with a difference in median PTNT of -9 minutes (95% confidence interval, -12.3 to -5.7). This difference persisted when adjusted for relative tissue-type plasminogen activator contraindications. For each additional telestroke consult, PTNT decreased by 0.07 minutes for NVFs or NVAs (P=0.02 and <0.01, respectively). CONCLUSIONS: PTNT improves by ≈1 minute for every 14 consults for both NVFs and NVAs. Our findings support the importance of integrating telestroke training into supervised neurovascular fellowships to increase proficiency prior to independent practice and suggest that PTNT can be a benchmark for tracking proficiency.

During the 20 years since US Food and Drug Administration approval of IV tissue plasminogen activator for acute ischemic stroke, vascular neurology consultation via telemedicine has contributed to an increased frequency of IV tissue plasminogen activator administration and broadened geographic access to the drug. Nevertheless, a growing demand for acute stroke coverage persists, with the greatest disparity found in rural communities underserved by neurologists. To provide efficient and consistent acute care, formal training in telemedicine during neurovascular fellowship is warranted. Herein, we describe our experiences incorporating telestroke into the vascular neurology fellowship curriculum and propose recommendations on integrating formal telemedicine training into the Accreditation Council for Graduate Medical Education vascular neurology fellowship.

BACKGROUND AND PURPOSE: Enrollment into acute stroke clinical trials is limited to experienced tertiary centers with emergency research infrastructure. Feasibility of remote enrollment via telemedicine into an acute thrombolytic clinical trial has never been demonstrated. METHODS: Using telemedicine, our hub stroke research center partnered with two spoke community hospitals to jointly participate in a randomized, phase III adjunctive thrombolysis clinical trial in the first 3 h after symptom onset to expand recruitment of the trial. Eligible patients were successfully identified, consented, randomized, and received therapy/placebo at the spoke hospitals under real-time direction by hub trialists via telemedicine. RESULTS: Ten patients were identified from May 2013 to July 2014, and six were enrolled via telemedicine. No study procedure delays, safety events, or major protocol violations occurred. CONCLUSIONS: It is feasible to randomize and enroll stroke patients via remote telemedicine into an acute thrombolytic clinical trial. This novel approach could expand access and accelerate completion of clinical trials if widely implemented.
RESUMEN
BACKGROUND AND PURPOSE: Prehospital evaluation using telemedicine may accelerate acute stroke treatment with tissue-type plasminogen activator. We explored the feasibility and reliability of using telemedicine in the field and ambulance to help evaluate acute stroke patients. METHODS: Ten unique, scripted stroke scenarios, each conducted 4 times, were portrayed by trained actors retrieved and transported by Houston Fire Department emergency medical technicians to our stroke center. The vascular neurologists performed remote assessments in real time, obtaining clinical data points and National Institutes of Health (NIH) Stroke Scale, using the In-Touch RP-Xpress telemedicine device. Each scripted scenario was recorded for a subsequent evaluation by a second blinded vascular neurologist. Study feasibility was defined by the ability to conduct 80% of the sessions without major technological limitations. Reliability of video interpretation was defined by a 90% concordance between the data derived during the real-time sessions and those from the scripted scenarios. RESULTS: In 34 of 40 (85%) scenarios, the teleconsultation was conducted without major technical complication. The absolute agreement for intraclass correlation was 0.997 (95% confidence interval, 0.992-0.999) for the NIH Stroke Scale obtained during the real-time sessions and 0.993 (95% confidence interval, 0.975-0.999) for the recorded sessions. Inter-rater agreement using κ-statistics showed that for live-raters, 10 of 15 items on the NIH Stroke Scale showed excellent agreement and 5 of 15 showed moderate agreement. Matching of real-time assessments occurred for 88% (30/34) of NIH Stroke Scale scores by ±2 points and 96% of the clinical information. CONCLUSIONS: Mobile telemedicine is reliable and feasible in assessing actors simulating acute stroke in the prehospital setting.
